DESCRIPTION OF THE PREFERRED EMBODIMENTS

A water conveying system in accordance with the present invention hastwo hollow water conveying members through which water can flow from afirst water supplying element, for example a fixedly mounted watersupplying pipe, to a second water supplying element, for example ashowerhead, and which are turnable relative to one another about aturning axis, for example to change an orientation of the second watersupplying member and also of water flow issues from the latter.

The first water conveying member is identified with reference numeral 1.It has a first opening 2 forming an inlet and having a first axis A-A, achannel 3 extending from the first opening 2 and having an axis parallelto the axis A-A, and a through hole 4 extending from the channel 3 alonga turning axis B-B. The opening 2 is used for insertion of a first watersupplying element and is provided with first connecting means formed asan inner thread engageable with an outer thread of the first watersupplying element when an end part of the latter is inserted into theopening 2.

The second conveying member is identified with reference numeral 5. Ithas a second opening 6 forming an outlet and having a second axis C-C, achannel 7 extending from it and having an axis parallel to the axis C-Cand a through hole 8 extending from the channel 7 along the turning axisB-B. A part of the second water conveying member, in which the secondopening 6 is formed, is provided with connecting means formed as anouter thread engageable with an inner thread of the second watersupplying element when an end part of the latter is pushed onto theabove mentioned threaded part of the second water conveying member.

The first water conveying member 1 has a portion with a concave surface9, while the second water conveying member has a portion with a convexsurface 10 congruent with the concave surface 9, so that when the firstand second water conveying member 1 and 5 are assembled with one anotherand turn relative to one another the surfaces 9 and 10 are slidable overone another, preferably with a sliding contact.

In order to assemble the first and second conveying members with eachother, they are first brought into a contact with each other so thataxes of their holes 4 and 8 coincide with one another and with theturning axis B-B, and then connecting elements connect them with eachother. In this position the axes A-A and C-C of the first and secondwater conveying members 1 and 5 coincide with one another and form acontinuation of each other. A first connecting element 11 is formed forexample as a threaded bolt and inserted into the aligned holes 4 and 8of the water conveying members so that its head is located in a part 12of the hole 1, and the second connecting element 13 is formed forexample as a nut and is introduced into a part 14 of the hole 8, to bescrewed onto a threaded portion of the threaded bolt.

A first seal 15 is provided between the first connecting member or thethreaded bolt 11 and the first water conveying member 1, a second seal16 is provided between the water conveying members 1 and 5, and a thirdseal 17 is provided between the second connecting member or the nut 13and the second water conveying members. The seals extend transversely tothe turning axis B-B and are coaxial with it and with each other.

When for example the second water conveying water member 5 is now turnedrelative to the first water conveying member 1 to provide a desiredangle between them and thereby a desired orientation of the outletopening 6 relative to the inlet opening 2 and thus a desired orientationof the second water supplying element relative to the first watersupplying element, and the nut 13 is tightened on the bolt 11 all sealsaxially compressed and immovably retained in their respective receivingopenings with full water-tightness and the first and second waterconveying element are immovably fixed with one another in a selectedangular position.

The alignment of the axes A-A and C-C of the water conveying membersprovides for a novel construction of the device, which takes less spacein the direction of the turning axis B-B and which prevents a sideoffset of the water supplying elements and provides their coaxially.

As described hereinabove the water conveying members can be assembledwith one another and convey water directly through the thusly formedunit from one to the other water supplying element.

In accordance with the present invention, a water conveying pipe 21 isprovided to realize a water flow from one of the water supplying elementto the other water supplying element through the water conveying pipewhose ends are connected with the water supplying element via acorresponding one of the water conveying members.

FIG. 13 shows that one end of the water conveying pipe 21 is connectablewith a not shown left water supplying element through the waterconveying member 1, while its opposite end is connectable with a notshown right water supplying element through the water connecting member5.

FIG. 14 shows that both ends of the water conveying pipe 21 can beconnected with the not shown water supplying elements by two waterconveying members 1, while FIG. 15 shows that both ends of the waterconveying pipe 21 can be connected with the not shown water supplyingelements via two water connecting members 5.

The water conveying pipe has a central throughgoing passage 22 extendingin a direction of its longitudinal axis and communicating with anopening 23 and a channel 24 at one end and with an opening 25 and achannel 26 at another end, for a continuous water flow through all ofthem. The surfaces 27 and 28 at one end and 29 and 30 at the other endare configured to be compatible and form receptacles for correspondingparts of the water conveying members 1 and 5. The openings 24 and 26 areformed with axes D-D and E-E to coincide with the turning axis B-B ofthe water conveying members when they are assembled with the ends of thewater conveying pipe 21.

When the water conveying members 1 and 5 are assembled with the waterconveying pipe 21 as shown in any of the variants of FIGS. 13, 14, 15,the same fixing elements 11, 13 are used to tighten the connections, tohold the water conveying members in a desired angular position relativeto the water conveying pipe, and to compress the seals between thethusly assembled components of the system. The seals can be introducedinto depressions 31 and 32 at the corresponding ends of the waterconveying pipe 21.

In this embodiment the water supplying elements are connectable with oneanother through the water conveying pipe and two water conveyingmembers.

When all components of the system are connected with one another andwith the water supplying elements, the central water passage of thewater conveying pipe 21 is in a water flow communication with the waterpassages at the ends of the water conveying pipe, the water passages atthe ends of the water conveying pipe are in a water flow communicationwith the water passages of the water conveying members, and theoutlets/inlets of the water conveying members are in a water flowcommunication with the water conveying elements.

The invention is not limited to the details shown since variousmodifications and structural changes are possible without departing fromthe main spirit of the inventive system.
